Though the casting announcement came as something as a surprise, there’s nothing better than photographic evidence.

Murphy showed off the first photo of Nicks on the set of “Coven” this week, wearing flowy black clothing and boots that manage to perfectly fit both the singer’s trademark style and the show’s dark aesthetic.

While the showrunner confirmed that Nicks will appear as herself in the show, the real question is what she will sing.

That’s right, Murphy suggested that the legendary singer will duet with Lily Rabe’s Misty Day, whose character has a full-on obsession with “The White Witch.”

According to “Entertainment Weekly,” Jessica Lange’s character will bring “Stevie Nicks in as a gift to Misty to prove to her that if she exhibits more power she’ll get that and more.”

At the time, Murphy told “EW” that the writers will still figuring out which song the duo will sing together.

“American Horror Story” airs Wednesday nights at 10pm on FX. What do you think Stevie should sing on the show?
